A rectangle object is perhaps the most versatile object type. You can use it to add page elements such as frames, panels, borders, or boxes. You can create squares, rectangles, or rounded rectangles. Rectangle objects can be made into hyperlink buttons that when clicked allow your visitors to navigate to other web pages.
Because a rectangle object can accept just about any shading component available (except image brightness and contrast), including flat or gradient colors and scaled, stretched, or tiled images, you can make a rectangle look dramatically different than just a plain four-sided box. Don't forget to try applying scaling, skewing, or rotation transformations to your rectangle for even more interesting effects.
The mouse pointer will become a crosshairs, and the rectangle object will display two small control points at the top left and bottom right corners, each flanked by two tiny "x's".
A small red control point will appear at the release point.
a rounded corner will be created that connects the two points.
The rounded rectangle object is drawn on the page.
